Seven Dragons' Den 'failures' that went on to earn millions

Dan Cluderay appeared on Dragons' Den in 2015 to ask for a £150,000 investment in exchange for a 10pc stake in his Approved Food online company.

His business ended up being rejected by all five investors, but it is now making millions.

Approved Food sells groceries and drinks that have hit their best-before date at a significant discount, saving customers around £60 on their monthly shop compared to high street prices, it claims. The shop also saves millions of food items from going to landfill.
